HOW DOES IT WORK?1. Water enters a spring-loaded chamber which creates a small pressure drop. This pressure drop immediately initiates the formation of calcium hardness crystals.2. The calcium hardness crystals pass through a catalytic surface which greatly multiplies the number of crystals. We have patented these two steps and this is what sets us apart from similar products.3. The next step has the calcium crystals pass through a strong magnetic field which serves to hold the crystals in suspension for up to 72 hours rendering them harmless to your plumbing, water appliances, and plumbing fixtures. This process bonds the calcium ions to each other rather than to your plumbing. The ESF will produce water that is much easier to clean (water spots) and no elbow grease is needed. In addition, the surface tension of the water is greatly reduced, resulting in a higher quality of water absorption in the human body and plant life.
